, "IMPROVEMENT vIhl UMBRELL-AS.

TO ALL W-HOM T MAY CONCERN: i Be itknown that we,-C H ARLES`M. MINOR, of Bridgeport, in the County of Fairfield, and State of Connectient, and HENRY S. FROST, of Watertown, in the countyof Litchfield, and State of Connecticut, have invented a new Improvement in Umbrellas; and we do hereby declare the following, when taken in connection with the accompanyingdrawings, andthe letters of reference niarkedthereon, tothev a full, clear, and exact description oi' the sume, end which said drawings constitute part of this specification, and represent, ini Figure' 1, a side view, one of the bows and brace attached in the position as opened.

Figure 2, the same folded.

Figure 3, an upper side view of the same in an open position. Y

Figure 4, an lupper side view Closed; and -n Figure 5,- a transverse section.

This invention relates to' animprovement in that class of umbrellas which are constructed with jointed bows, so as to fold into a compact form; `and consists, r'st, in constructing the one part of the bow so vas to form a latch for the other part when o'pen; and, second, in hi'ngin'g the two parts of the bow andthe bruce to one and the same piece;

I To enable others to constructr our improvement, we will proceed to describe the same,l as illustrated in the accompanying drawings. l

a is the one part of. the bow, b the other part,` and 'e the'lniac'e.l The part a, which we employ as the upper part, is formed from wire bent as denotedin fig. 3, so as fo forma ,loop at the end, and the end turned around und united to the body of the wire/at al, and thesaid loop is bent down as at f, figs. 1 and 2;v then within the loop isos-st or fixed solidly a block,lz', extendingV down, so thatl the brace c may be pivotc'd thereto, as seen in figs. 1, 2, and 5, and into the said block t' the other part, b, of the bow is pivoted, as-seen in figs, 2 and 3, Vand so ns'to turn freely onlitspivot from the'position ing. 1 to that in iig. 2.v The loop at the point p is a little narrower thanthe diameter of the part'b, as denoted in iig. 4,.opening a littlefrom that point toward thel extremity of the loop, so that when the bowr is turned down to the positionin g. 1, it is pressed down into the bow at the narrow point, and springs into the extreme end of the loop, and is there held by the narrower portion or point of the loop, but yet so that'it may be easily turned up therefrom. Thus, whenthe umbrella is being jointed or pivoted, substantially as set forth,

extended,and the user desires to .fold the same, turnA up the partb of the 'several bows, as denoted in figs. 2 and 4, and the umbrella is foldedinto nearly halfv its usual length. Thus we form Va cheap and durable lock joint for the bows. v A

Having thus fully describedour'invention, what we claim as new and useful, and desire to secure by Letters Patent, is-

brace the other part therein, substantially as set forth.
